FREDERICK C. OVERBURY",l F NEW YORK, N. Y., ASSIGNLOR. TO FLINTKOTE MANU` FACTURING COMPANY, 0F RUTHERFORD, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all rLohom 'mlay concern:

Be it-known that I, FREDEEICI: C. GvEn- BURY, of'New York-,in the county of New York and 4State of New York, have invented certain new and useful Improvements in. Roofing- Aasteners, of which thefollowing is a specification. y

This inventionlrelates to means for secur-' ing-roofingmaterial to supportin surfaces of a nature capable'of receivingv riven fastenings lwhiclr'penetrate the roofing material and aefdriven into vthe supporting surfacel whichisigenerall of wood. By thisl, mean to distinguish rom interlocking fasf tenings comprising, two members one of :.which is attached tothe supportingl surface and the other carried by 'the under side of A the material and the two interlocked; Such devices may'attain their object of avoiding liability of causing leaking, but vthey are 'more expensive 'than drivenl fastenings and more difficult toapply.l

The p'rlncipal ob] ect of my present invention is-to provide .an improved fastener"l which, While perfectly securlng thecovering material to the supporting surface, will permit ,of-` suiiicientsllp of the material rela "'t-ivel tot the fastenings to vprevent the matel' rial rombuckl'ing if it expands or contracts under changes 1n atmospheric condltions, or',

' due to length ofA ex osure. l

Another object o my invention is to prod-I"A vide fastenin'gs `f the driven ty e which' will secureweather-proof materla to supporting surfaces, the fastenings connecting overlapping sections of the protecting material and also securing them to the supportillustrate the invention for roofin l although Ait may be equally` as We l uti ized ing surface, but in such manner that. every -punctured part of a section of material is protected, to prevent passage of water, either erlying unperfof by 'an overlapping or un rated layer of material. i

To these ends, the invention consists in the fastening, and in the combination, substantiallyV as hereinafter described and.

claimed. l

, one form of my improved'l fastening. Fig. Q -re 'rese'nts a 'section-on 1ine'2-2 of Fig. 1 on 'a arger scale. F-ig. 3 is a perspective view 4 of the fastener shown in Figs. 1 and 2.

Figs. 4, 5 ando, are er'spective views of modified forms of the 1 astener. Fig. 7 is a plan view of a portion `ofroofing material eld by the fastening shown in Fi 5.

Similar reference characters in ica-te thev same or similar parts or features in all of Referring first to Figs. 1, 2 and 3, .the Supporting surface 10 may be understood as a, portion of a roof ,structureon which th'e overlapping layers or strips of roofin `material 11 are secured by my improved fastenings. Said strips are shown as,of the serrated type, having what are calledin the trade diamond points ll.. My invention lis especially designed for this type of roofing material, )as it provides for holding the points down Without furnishing or causing perforations communicating through the several layers tothe support 10 such as.

would permit access of Waterthrough to said support'. The'inventionis not limited however tothis 'particular type of materia The fastener comprises an elongated body 12:havig-an' u wardly turned prong 13 -and'one or 'more oles 14 which furnish the `meansto enablenth device to be attached to :the suppprtin `surface by suitable nails 15 roug said'hfolesj. i

y usually rolled up a'nd when laid first 'has-onegnd attached in properpostion, and"the siefeeding fasteners are4 applied as .thevmatei'lliis unrolled. It will be readily understood that in the use of my Cpresent. invention, each fastener is attache in position before the strip 'which is to overlie it is laid'or unrolled. As it is unrolled, eachupstanding prong 13 is driventhrough it, and then said prong is bent down in a direction 'away froml the point Where the fastener has been attached to the vsupporting surface, so thatthe fastenerv a's a whole ies'almost in 'a continuous plane. This act4 of bending the prong down, slightly' lifts up the sheet material above ythe point .where the prong has;y.been forcd t e prong being preferably hammered down as indicated at 13u until it is almost in the 125 points-'11a plane of the body portion 12, leaving only a slight offset whlch will permit the materlal to Yslip sufficiently along said offset portiontoavoid hurl ling if the material. expands. and to avoid a-ny enlarging of the aperture .around the prong when the material con: f tracts.

Instead of employing nails 15e passing through holes .1l in the 4body ,of the fas-t tener, the means whereby .the fastener may "abe attached to the supporting surface may comprise integral portions 'of said' body. For instancethe body may be of wire as at v 1Ql in Fig. 4, the ends being bent to form attaching points 15a-,an intermediate portion being bent to forni an upwardly projecting t prong 13a the tip of which may if desired, be flattened sufficiently to enable it to be driven readily through the roofing material, The device in this form Lis used in the samev manner as has been described in connection with Figs.. 1, 2 and 3.

In order to provide additional prong members which will serve to hold down the of the material, and still'not interfere with the slip which hasbeen described, I may provide a small strip fof metal such as indicated at 16 in Fig. 5y having upturne-d prongs 16a. This strip 16, when used, is placed under the lower end of the body portion 12, so that when the roofing material is forced down over all three ofthe prongs 16a and 13, the said prongs may bend down flat upon the material, as shownin Fig. 7. As the strip 16 is Ifree to'slide in anyV direction relatively to t-he'bar or body member l2 no obstruction vto the slipping-` or sliding ofthe rooting material-'relatively to the .body of the fastener is provided.4 40 But this pronged strip 16affords additional` means 'for preventing the points 11u of the roofing material from' being loosened i and turned up. v l v As shown in lFig. 6, the body 12b need not have an integralupturned prong. Instead, I may provide a three-armed plate 13b, each arm of said .plate being upturned to form pron-g 13C. Then said prongs 13 are forced through the roofing material and 50 bent downin the direction above described,

the slipping or sliding movement is provided for. byreason of the Vplate 13bbeing free to move in any direction under the lower end of the body 12b.

In each form shown, the structure is such that the fastener'presents an elongated portion whichlies concealed -under a strip of covering material andhas means whereby lit' may be attached to a supporting surface, one or more upwardly p rejecting prongs being provided which are out, of alinement j with the attaching means.A Therefore, it is impossible for any moisture which might. .find ils way around the prongs', from work-v ing' up to a. point where it might find its`l` way through 'the underlying strips around the-attaching means. At the same time, the holding prongs do not interfere with ,such expansion orcontraction of the material asA may occur undei"varying conditions of the 'IJ atmosphere, or due' to the length. of time`- thatthe rooting material has been-laid, be'` cause of .the direction in --which =-they lie after the final' act of bending iscorrrpleted.

It will be understood that the several fas- 75 teners co-act with each other through the several overlapping layersY of 'rooting material, so that each fastener 1s aided 1n v its securingl functions by adjacent fasteners,

Each fas-tener is secured to the sup-porting 3o surface entirelyl underneath portions :of the f roofing material, and is soarranged that it* will not only hold` down the overlying sec` tion or strip ofrooting material, but will permitthat overlying section 'to -e'xpand v85 and contract without'showingjany buckling 'at the surface.

Having now' described myinvention,- what y I claim is I l f i 1. Thecombination with a supporting surface of va plurality ofstrip's orlsheets of rooting material each havinga serrated edge,

al fastener 'comprising asinglestripjof material forming an elongated'body portion constructed to lie concealed under said roofing 9 5 material, said fastenerstrip bengprovided with means whereby it may b`e attached to sa'id,supportingsurface, one end of said fas-v tener strip beingarranged at an angle to the' body thereof, and passedrt-hrough one of the `serrated projections of the overlying roofing st.-rip, said angular portion being flexible and bent in a"direction away fromfsaid body. to.

permit said roofing material to expand and -ontraet withoutgbuckling between the prong and `the`attaching means, thetop Yface Iof said body being free of upwardly projecting protuberances, -Y

2. Thelconbination with a supporting surface of aplurality of strips or sheets of'roof- 110 ing material each having a serrated edge, a fastener comprising asingle strip of' material forming an elongated body portion constructed to lie concealed under said roofing material, and arranged to lie at right, anglesll tosaid roofing strips, one end of each fastenfing being passed through one of the serrated `projections "of the overlying roo-fing strip.'

and continuing beyond the point of penetration in a direction in line with the body of 120,1"
